New types of fungal pathogens, a drastic decline in the number of flowering plant species, the increased use of agricultural chemicals, and climate change are partially responsible for the worldwide plight of bee colonies, claims a new report released Thursday by the UN Environment Program (UNEP). The study, entitled Global Bee Colony Disorders and other Threats to Insect Pollinators, fingers more than a dozen possible factors, all of which have contributed in some way to the decline of the...

Scientists are seeking a way to identify and eliminate mass deaths of the honeybee, the primary pollinator for the world's plants. The die-offs affect more than 30 percent of bee colonies in the United States and more than 20 percent in some European countries. A few possible causes identified in Colony Collapse Disorder (CCD) include blood-feeding parasites, bee viruses, fungi, pesticide exposure and decreased plant diversity causing poor nutrition for honeybees, experts tell Reuters....

Beekeepers in Australia called on the government this week to accelerate efforts to eradicate the devastating Asian honeybee while it still has a chance. The aggressive bees were first detected in far north Queensland about four years ago, and have the potential to wipe out the entire industry. Known as Apis cerana, the Asian honeybees also attack birds, raising concern for local fauna.  They could be as bad a pest as the cane toad, warned Australian Senator Christine Milne on...

US researchers claim to have identified a potential disease responsible for Colony Collapse Disorder (CCD) in honeybees, which is responsible for wiping out many beekeepers' entire colonies over the past few years. Scientists from the US Department of Agriculture say the pathogens to blame are a fungus and a family of viruses. Results of the study were presented Tuesday at the 110th General Meeting of the American Society for Microbiology in San Diego, California. Jay Evans of the USDA...

The World Organization for Animal Health (OIE) said Wednesday that the dramatic die-off of honey bees around the world, threatening crops that rely on the insects for pollination, is not due to any one single factor. The OIE said that a host of issues are plaguing the honey bees - including parasites, viruses, bacterial infections, pesticides, and poor nutrition resulting from the impact of human activities on the environment. Bee colonies naturally lose about 5 percent of their populations...

Research suggests that the decline of honeybees seen in many parts of the world has been caused by the reduction of plant diversity, according to BBC News. The scientists found that bees fed on pollen from several plants had a healthier immune system than those eating pollen from a single type. The French team wrote in the journal Biology Letters that bees need a fully functional immune system in order to sterilize food for the colony. Other research has shown that bees and wild flowers...

Ground-breaking discoveries by Michigan State University researchers could help protect honeybees from deadly parasites that have devastated commercial colonies. The MSU researchers for the first time were able to produce in the laboratory proteins that help channel sodium ions through cell membranes of parasites known as Varroa mites. The research, using cellular frog eggs, also found that these proteins react to chemicals differently than the sodium channel proteins in honeybees, a finding...

Scientists at Rothamsted Research and Warwick University have been awarded £1M (1.5M USD) by the Biotechnology and Biological Sciences Research Council (BBSRC) in partnership with Syngenta, to research the decline of honeybees. UK government figures suggest bee numbers have fallen by 10-15% over the last 2 years; the British Beekeepers' Association (BBKA) quotes a figure nearer 30% for 2008. Since the declines were first reported a number of factors have been suggested. Most scientists...

In an attempt to counteract the disappearance of bees, Britons are beginning to keep their own bees in small urban gardens. Beekeeping is an age-old practice that is now making a come-back in Britain, as people become increasingly worried about the future of food and a strong desire to make a difference in the environment. Only 6 months ago, 43 year-old Jon Harris was just learning how to keep bees, now he has a successful hive in his small back garden in Brixton, south London. "That...

Attendees of this year's Apimondia, the 41st world apiculture congress, in southern France are focusing on what is killing the world's bees. Pesticides, viruses, industrialized farming and fungus are among the possible reasons why bee hives throughout parts of North America, Europe, and Asia have been struck by a mysterious ailment known as Colony Collapse Disorder (CCD).  Although bee communities naturally lose around five percent of their numbers during normal times, up to 90 percent...
